Home Forums Reloading Big Game Rifles 280 Ackley Loads with Barnes 140 Grain TSX or TTSX

Well I called Barnes and they didn't have any data for IMR4831.

So I'm starting with the Nosler data and loaded up some .05" off the lands and starting load was the minimum charge of 56 and worked my way up to 60.

56
57
58
58.5
59
59.5
60

I'll be watching the case head expansion and see where this goes.
